Re: pagination and groups
2011/7/1 Tomás Fernández Löbbe tomasflo...@gmail.com: I'm not sure I understand what you want to do. To paginate with groups you can use start and rows as with ungrouped queries. with group.ngroups (Something I found a couple of days ago) you can show the total number of groups. group.limit tells Solr how many (max) documents you want to see for each group. Right - just be aware that requesting the total number of groups (via group.ngroups) is pretty memory and resource intensive - that's why there is a separate option for it. -Yonik http://www.lucidimagination.com
Re: pagination and groups
Hey, I don't suppose you could easily tell me the rev in which ngroups arrived? Also, how does ngroups compare to the 'matches' value inside each group?

Grouping originated in Solr, was refactored to a shared lucene/solr module, including the ability to get the total number of groups, and then Solr's implementation was cut over to that. Also, how does ngroups compare to the 'matches' value inside each group? The units for matches is currently number of documents, while the units for ngroups is number of groups. -Yonik http://www.lucidimagination.com

What takes the place of response.response.numFound? 2011/7/1 Tomás Fernández Löbbe tomasflo...@gmail.com: I'm not sure I understand what you want to do.

Re: pagination and groups
are you using group.main=true? I didn't see the code for this and the documentation doesn't specify it, but I tried group.ngroups=true and using group.main=true, the ngroups attribute is not brought back. If you are not using group.main=true, then by setting group.ngroups=true you'll see the value ngroups which means the number of groups that matched the query. NOTE: All this is in trunk, I'm not sure if it is on 3.3 On Fri, Jul 1, 2011 at 3:53 PM, Benson Margulies bimargul...@gmail.comwrote: What takes the place of response.response.numFound? 2011/7/1 Tomás Fernández Löbbe tomasflo...@gmail.com: I'm not sure I understand what you want to do.

Re: pagination and groups
I'm using a version taken from the trunk some time ago. I'm not setting groups.main, I just started setting groups.ngroups, and nothing doing. So I guess I don't have a new enough grab from the trunk. 2011/7/1 Tomás Fernández Löbbe tomasflo...@gmail.com: are you using group.main=true?
